Answer:
1/ab
Step-by-step explanation:
Complete question
Find the slope of the line containing the points whose coordinates are(a,1/b) and (b,1/a)
Slope is expressed as;
m = y2-y1/x2-x1
Substitute the coordinate values
m = (1/a - 1/b)/b -a
m = (b-a)/ab ÷ b-a
m = (b-a)/ab × 1/b-a
m = b-1/b-a × 1/ab
m = 1 × 1/ab
m = 1/ab
Hence the slope is 1/ab
